Life Extension's Super R-Lipoic Acid has demonstrated superior bioavailability, stability, and potency for a variety of health benefits. This breakthrough converts the biologically active "R" form of lipoic acid to sodium-R-lipoic acid, which, in a recent human study achieved 10-30 times higher peak blood levels than pure R-lipoic acid. Not only does this newer lipoic acid formulation reach higher peak blood levels, it also achieves them sooner, ensuring rapid uptake from the plasma into the tissues. A recent study showed that oral ingestion of Life Extension Super R-Lipoic Acid reached peak plasma concentrations within just 10–20 minutes of supplementation.*

Unlike other forms of lipoic acid, Super R-Lipoic Acid is more stable in the body. The increased stability of this enhanced formulation is the reason for its greater absorption and bioavailability compared with R-lipoic acid. The superior antioxidant effects of R-lipoic acid are already well known for supporting healthy mitochondrial function. Now, Super R-Lipoic Acid provides even more potent benefits for preserving youthful cellular energy levels.*
